Series describe the horizontal rows in the periodic system. Every series has its own theme, its own area of problems. The word series also indicates that there is a progressive line of development from one series to the next.
For practical reasons I have named each series after its most characteristic element. The rows below Ferrum have been called Silver series and Gold series, after their most well known elements. The second series is called Carbon series, and the third Silica series.
To give you an impression of the correlation between the series I have written a brief summary below. A more extensive description will be given at the start of each chapter.
